Space probes have significantly expanded our understanding of the solar system by collecting detailed data from various celestial bodies. They have provided invaluable information about the composition, atmosphere, and geology of planets and moons, revealing phenomena such as volcanic activity on Io and the intricate rings of Saturn. Additionally, missions like Voyager have traveled beyond the solar system, offering insights into the heliosphere and interstellar space. Overall, these probes have transformed our view of the solar system, uncovering complexities that ground-based observations alone could not achieve.
The Pioneer and Voyager space probes primarily used radioisotope thermoelectric generators (RTGs) as their energy source. These RTGs convert the heat released from the decay of radioactive isotopes, typically plutonium-238, into electricity, allowing the probes to operate over long periods in the cold, dark regions of the outer solar system. This method provided a reliable and long-lasting power supply, essential for the probes' extended missions.
Telescopes, Pictures,Satellites, and Probes
While many space probes near the Sun (or not too far away, like satellites near the Earth) are solar powered, the designers of the Voyager probes knew that the spacecraft would be going out from the solar system to distances where the Sun is merely a bright star. So the Voyager probes use a nuclear thermal power source.
Lunar probes are spacecraft designed to study the Moon's surface, atmosphere, and geological features. They gather data on lunar composition, topography, and mineralogy, often using various scientific instruments like cameras and spectrometers. Additionally, probes can conduct experiments to understand the Moon's environment and its potential for future exploration. Their findings contribute to our knowledge of the Moon's history and its role in the solar system.
There is much space debris. Humans have many decayed satellites and probes floating around.
Without space probes, the only knowledge we have of the solar system comes from ground-based telescopes. That's how we did it for 300 years before satellites.

Space probes are crucial for space exploration as they allow scientists to gather data from regions of the solar system that are otherwise unreachable by human missions. These unmanned vehicles are equipped with advanced instruments to study planetary surfaces, atmospheres, and other celestial phenomena, providing invaluable insights into the origins and evolution of our solar system. Additionally, space probes can operate in extreme environments for extended periods, enabling long-term studies that contribute to our understanding of space and its potential for future exploration and habitation.

No, the Voyager mission involved two space probes, Voyager 1 and Voyager 2, which were unmanned spacecraft launched by NASA in 1977 to explore the outer planets of our solar system. The probes have continued to travel beyond the solar system into interstellar space.
Voyager 1 and Voyager 2. There is a matter of some debate as to whether the two Voyager probes have actually left the solar system, an where the "edge" of the solar system actually is. Both are beyond the orbit of Pluto, but have not passed beyond the vaguely-defined Kuiper Belt, and the two probes are just approaching the heliopause, the boundary layer between the solar wind and the broader currents of interstellar space. But it seems likely that however that boundary is defined, the two Voyager probes either were or will be the first man-made objects to pass it.

In the solar system, we have a star, planets, dwarf planets, asteroids, comets, meteors, and human debris. (such as old satellites, probes, etc.)

The Voyager 2 went to Neptune on it's last stop in the solar system.
